Well, this is most excellent.

Alex Winter, who famously played Bill in the 1989 teen classic Bill and Ted’s Excellent Adventure and its 1991 sequel, Bill and Ted’s Bogus Journey, gave fans a peek behind the scenes of the original on Wednesday, after he found an old hard drive.

They show Winter and his co-star, Keanu Reeves, working on scenes that didn’t make it into the final cut of the film about two failing high school students who travel through time to find historical figures, such as Abraham Lincoln and Socrates, for their school presentation.

Winter described an “opening dance number,” which he specified was “yes an actual, choreographed rock jam,” and an opening scene in which the aspiring rockers encounter jocks at the school bus stop.

I found an old hard drive with a bunch of BTS shots from Bill & Ted 1. These are from the opening dance number (yes an actual, choreographed rock jam) and face off with the jocks at the bus stop that didn’t make it into the movie: pic.twitter.com/xFSSeVAzSy
